Marine anti-backflow floor drain and installation method

Abstract

The invention provides a marine anti-backflow floor drain and an installation method, the marine anti-backflow floor drain comprises a floor drain cover, a floor drain body, a track and an anti-backflow device, the four structures are detachably assembled together without welding, the required occupied space is saved, the influence of no welding space of a ship is avoided, and corresponding parts can be maintained or replaced and detached in the later period; the floor drain cover is of a double-filtering structure, impurities such as fibers and large particles can be prevented from entering a pipeline and an anti-backflow device, and the pipeline is effectively prevented from being blocked. The opening part of the floor drain body is subjected to rubber vulcanization treatment, so that the contact surface of the opening and a hull structure can be effectively sealed, and water leakage and seepage are prevented; the surface of the baffle limiting stopper is subjected to rubber vulcanization treatment, so that rigid connection between the clamping groove and the baffle limiting stopper is avoided, and the effects of damping and noise reduction are achieved; the anti-backflow device integrates the functions of backflow prevention and peculiar smell prevention by ingeniously using the reducing pipe and setting the lowest height of the anti-backflow outlet to be higher than the height of the circle center of the floating ball falling on the floating ball blocking piece.

Description

technical field [0001] The invention relates to the field of floor drain design, in particular to an anti-backflow floor drain for ships and an installation method. Background technique [0002] Ship floor drains are usually used in places that require drainage such as decks, showers, kitchens, etc., and the usual floor drains are welded and have a relatively simple shape. The usual reference standard is CB / T 3885-2014. Floor drains used in rooms and cabins such as kitchens and showers usually adopt the form of designing the pipeline into a U-bend or adding a clarifier water seal to the pipeline. However, the form of the U-bend water seal needs to be based on the size of the pipe diameter and the size of the bending die. The installation space is determined by the size, and the clarifier also needs a certain layout space, so there is a problem of occupying a large space, and most of the components are scattered, and it is impossible to integrate anti-drainage and anti-odor. ...

Problems solved by technology

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a marine anti-backflow floor drain and its installation method, which is used to solve the problem that the floor drain in the prior art uses welding, takes up a lot of space, and most of the components are scattered. And the problem of the inability to achieve the integration of anti-backflow and anti-odor
